GCOM-4000-VOCs Water Volatile Organic Compound Online Analyzer Introduction: GCOM-4000-VOCs are composed of a headspace sampling module and a high-temperature chromatographic analysis module (GC-FID). It can monitor volatile organic pollutants such as benzene, toluene, xylene, ethylbenzene, styrene, etc. in industrial wastewater and surface water processes. Pump the water sample into the headspace tank of the analyzer through a pre-treatment pipeline; Under constant temperature heating conditions, the volatile organic compounds in the water sample are transferred to the gas phase space above the liquid surface, and then the volatile sample gas is transferred to the high-temperature chromatographic analysis module for detection by pressurizing and reducing the carrier gas. The process of transforming liquid into gas phase through a headspace sampling device allows for direct measurement of volatile clean gases. It can overcome the influence of impurities (such as suspended solids) in water on the analysis of flow paths. Application: Used for monitoring VOCs in wastewater discharge from industries such as coatings, resins, pharmaceuticals, concentrated drinking water, and surface water sources. Features: 1. By using a headspace sampling device to phase change the liquid into a gas phase, it is possible to directly measure the volatile clean gas and overcome the influence of impurities (such as suspended solids) in the water on the analysis flow channel 2. After each sample introduction, the analyzer automatically blows the chromatographic column to accelerate the analysis and screening of components 3. The intelligent FID detector automatically ignites when the engine is turned off, effectively controlling the safety of the hydrogen flame gas channel 4. The internal pipeline of the chromatograph is subjected to silanization treatment, greatly reducing the adsorption residue of the gas sample on the pipe wall Technical parameters: Measurement method: GC-FID gas chromatography Measurement parameters: benzene series Range: 0-20mg/L Detection limit: 0.05mg/L Lower detection limit: 0.1mg/L Resolution: 0.01mg/L Indication error: ≤ 15% Qualitative repeatability: ≤ 1% Quantitative repeatability: ≤ 10% Measurement cycle: ≤ 1h Communication protocol: Modbus RTU/GB2017 Size: 800mmx800mmx1865mm IP level: Cabinet IP42 Power: 220VAC, 1500W Working temperature: 5 ℃~45 ℃ Working humidity:<95%, non condensing Compressed air: (0.4~0.8) MPa, clean and oil-free Carrier gas: nitrogen, purity ≥ 99.999%
